PLAITING MACHINE.

Application filed February 21, 1923.

To all ill/LOH?- ?It may concern:

Be it known that I, MAE NOEL, a citizen of the United States, and aresident of Washington, in the District of Columbia, have invented certain new and useful Improvements in Plaiting Machines, of which the following is a specification.

This invention relates to a form pattern making machine.

The invention particularly relates to a machine for making form patterns of the character employed for plaiting skirts, ruffies, panels, etc., that is, for forming accordion, side or knife, box plaits or the like used in wearing apparel.

Patterns of the form above referred to are usually made of paper or the like having a suitable stiffness. The pattern consists of two layers criinped to correspond to the plait desired and are arranged in such a manner that one or more layers of goods can be placed between them. When plaiting a piece of material one layer of the form pattern stretched on a table. The material is placed on this and the second pattern is placed on top, the lines of both patterns corresponding. The material may now be folded. with the form patterns and then placed in a steam chest for a certain period. Upon removing the form patterns and material rein the steam chest the material will then have plaits similar to that of the form pat tern. Also if desired the form patterns with material therein may be ironed instead invention that the machine be adapted for substitution of parts and adjustments whereby diiferent form patterns may be produced or made.

it is also within the scope of the objects of the invention that the machine be exceedingly simple in construction and easy to manipulate.

Other objects, and objects relating to de- It is a further and important object of the Serial No. 620,551.

Figures 16, 17 and 18 are edge views of different forms of patterns which may be made with the present machine.

Like reference numerals refer to similar parts in each of the several views.

Referring to the drawings in detail the .machine may consist in a frame comprising the two side walls 1V and W which may be secured together by the rods B, said rods rods also serve to properly space the walls W and W from one another.

Between the walls W and W there is journaled the two shafts S and S said shafts being preferably in horizontal alinement and occurring adjacent the upper ends of the walls. The shaft S is forward to the shaft S. Upon the wall W there is mounted in a suitable manner an electric motor M,

said" motor carrying upon its driving shafta sprocket wheel 10 which is connected to a sprocket wheel 11" carried by the" shaft '8 through the means of a suitable sprocket chain 12; A sprocket wheel 13 is mounted upon each of the shafts S and S Whicli'are operativelyconnected to each other bythe means of a sprocket chain 14 whereby to impart'the rotation of the shaft S to the shaft S The shaft S is extended froin ea'ch of the walls and W and upon each end'of the shaft there is 'lnounted a cam' wheel 15. Each cam wheel is in the form of a disc andhaving formed upon its'inner surface a circular groove 16 whicli 'is provided with the diametrically opposed depressions '17' and p gaged thereby. Therollers R are each su ported by a pair of pins 21, the'pins alassociat'ed' withwall l/V being extended and each carrying a'cogwheel 22; Th'e cog wheels 22 are adaptedjto'be 'in constant mesh with one"another.- R there is mounted a crimping unit comprising the two cross bars 23 which are so spaced that the sheet of paper 20 may'pass therebetween. Each member 23 preferably has its'forward end beveled as at 24,-and its rear end provided with an offset portion 25; The offset portions 25 should terminate in close relation to the periphery of the rollers R Forward to the rollers R each side wall W and W is provided with a pair of arcuate shaped slots 26 and 27', which intersect each other in each instance as'at '26.

A pair of crimping rollers R and R are provided which are disposed between the walls WV and W and forward of the rollers The roller It is provided at each-of its ends with a pin 29 (Figure 2) ,"and eachpin 29 is disposed in the associated slot 27. The roller R is also provided at each end with a pin 30 and each pin is disposed in the asso- Forward of the rollers ciated slot 26. The one end of a link member 31 is pivotally connected to each of the pins 29 of the roller R and the other end ofeachlink 81 is pivotally connected to the associated side wall of the machine as at 32. A similar link 33 is likewise connected to each end of the roller R and each link pivoted to the associated side wall of the machine as at 34. Similar ends of the rollers are connected by a hnk 37. Upon each side of theinachine there 1S PIOVlClGd a'nfoperating'bar 35 forthe rollersR and 'R said bar in each instance being pivotally-connect ed at'its lower end to the associated link 37 mates."- 7 a 1 Each bar is pivetally connected at its upper end as at'et) to a bar 41. The bar 41 is pivoted at its rear end as at42'to the associated side wall of the machine and its forwardend :is provided with a suit- 1: able rolle'radapted to move in the associ-R atedgroove l6, said-roller'being supported bythe means of a'pin orthe like as lat 43.

upon theinn'er side of the ratchet wheel The co wheel 44 occurs 4:7. Tlie rat chet wheelie? is provided with teeth-49 approximately of the shape and size shown. The cog wheel 44 is in com stant a reshwith the lowermost associated cog wheel 22 whereby the rollers- R are driven i'n'opp'osite directions and thereby to draw the" sheet of paper 20 therebetween;

Theratchet wheei 47 is driven by'a re ciprocat ng bar btl, said reciprocating-bar being slidably held upon the side wall W of the machine by 'a suit'able boxing 51 and can rying a't-its forward end apawl 52 which is'a'dapt'ed toengage with the teeth ai9upon movement of the bar50 in a rearward direction; peningsea are provided in the" forward end of the bar-50 whereby the pawl 52inay beadjustedflTheforward end of the-bari50 i's -pivotally, connected as at 54 to the loii er' end of anactuating bar 55, said actuating bar being pivotaliy connected as at" 56 to the sidewall W'of' the machine at a point substantiallycentral of its length and at: its upper end carrying a roller 57' which is disposed to move in a groove 58 formed upon the outer surface of af-cam wh-eel59. ThQCaHI wheel 59 is in the form of a d sc and'the groove 58 therein islformed' with four protrusions the two protrusions 60 being diametrically opposedutoifeachv other and the protrusions 61 being similarly arranged. The cam wheel 59 is secured to the associated end of the shaft S and is held against turning movement by the means of a key as at 62. This cam may be turnably adjusted upon the shaft through the means of the different keyways shown in the hub of cam. This is also true of the cams 15.

Upon the stub shaft 48 exterior to the ratchet gear wheel 47 there is pivoted an arm'63, said arm being pivoted at a point intermediate its ends upon the stub 48 and its lower end is adjustably held by the means of a bracket member 64 which is secured to the wall W of the machine. The bracket member 64 consists in an arcuate shaped member having its ends formed with offset portions 65 which are secured to the wall W of the machine, and between these end portions the member 64 is provided with an elongated slot 66 extending substantially the entire length thereof. The lower end of the arm 63 has extending therefrom a suitable stud which is adapted to slide within the slot 66, and this stud has threaded thereon a suitable wing nut 67 whereby the arm 63 may be adjustably held. Suitable markings may be made upon the member 64, as shown, in order to accurately adjust the member 63. The upper end of the arm 63 carries a stub shaft 68 which in turn supports a collar or sleeve 69 of insulating material, said collar carrying a pair of slip rings 70. Suitably insulated contacts may be provided upon the upper end of the member 63, not shown, and electrically connected to the slip rings 70, said connections being made upon the inner periphery of the slip rings. Turnably mounted upon the sleeve 69 is a cup-shaped casting 72, said castin having formed at its free or outer end a dange plate 73 which terminates in an inwardly disposed flange 74. The casting} 72 is held upon the stub shaft 68 by a pin 75, the inner and free end of which extends into a groove 76 formed in the member 68. Upon the outer end of stub shaft 68 there is turnably supported a head or cap 77, the inner end of which terminates in ratchet teeth 78. A spring pressed pawl 79 carried by the stub shaft 68 holds the head or cap 77 against turning in one direction. Within the casting 72 there is positioned a spiral spring 7 9 having its outer end secured to the casting as at 80, and its inner end secured to the head 77. A plate 82 is fitted into the outer end of casting 72, said plate being rotatable about the head 77. The forward face of head 77 should be provided with a slot into which akey may be positioned for rotating the same to wind the spring 7 9. The plate 82 is secured to the casting 72.

Upon the flange portion 73 of the member 72 there is turnably mounted a switch casing generally indicated by the reference nuwithin the casing and secured thereto and this contact member is adapted to normally engage the finger 85. Each finger 85 and 88 is connected to a brush 71 through suitable means as shown in Figure 9 whereby to permit turning of the casing 83 and also permit rotation of member 72. The motor M heretofore referred to should be connected so that its supply of electric current must pass through the contact fingers 85 and 88. The manner in which the motor might be connected is entirely apparent and therefore not shown.

Upon the arm 63 there is secured adjacent its one edge a bracket arm 89 which is formed at its outer end with a sleeve 90 through which there slidably extends a rod 91. It is important to here observe that the casting 72 is formed so that it is disposed concentrically to the stub shaft 68. This structure is best illustrated in Figure 9 of the drawings.

The inner end of the rod 91 carries a latch member 92 which is adapted to engage a protrusion or lug 93 formed upon the inner periphery of the flange 74 and thus to loci: or hold the casting 72 against rotative movement when so urged by the spring 79. Adjacent the inner end of the rod 91 there is slidably mounted a sleeve 94 which is preferably square in cross section and which carries a set screw 95 by which the same may be adjusted upon the rod 91. The outer end of the rod terminates in a head 96 which in turn terminates in a body or semi-circular member 97 and between the head 96 and the sleeve 90 of the bracket arm 89 there is in terposed a compression spring 98. The member 97 carried by the rod 91 is adapted to be engaged by a pin 99 carried by the ratchet wheel 47. The ratchet wheel 47 has a plurality of openings 99 whereby the position of pin 99 may be changed.

The plate 82 is formed with an annular groove 100 which is eccentric to stub shaft: 68; and in which there is disposed a pin 101 carried by a block 101 which is slidable in a hollow arm 102, said arm being provided with a longitudinal slot 102 to accommodate the pin 101. The rear end of arm 102 is pivotally supported as at 103 adapted to permit free upward and downward swinging movement of said arm. The pivotal support fl03also providesa pivotal support for the bar 104, which, adjacent its free end is providedwitha downwardly curved portion105" to provide a substantially arcuate sliapecl; edge"surface 106 upon which the paw'l'52 ina'y ride." its shown in Figure 11, adjj agcent' the pivoted end of the bar 104-2; there is formed apair of diametrically opposed ears 107 to which there'is secured a brid member-108, said bridge member havi intermediate portion 109 which is pro sded The arm 102 7 spring 113 which is pivoted at its one end to the side wall of the machine as at114, and which is held against downward ing movement by a pin'fli l".

Upon the side wall W of the machine there is rotatably supported a disc wheel 115, the periphery of which is formed with a plurality of notches 116, said notches being preferably tour in number as shown. 'iho hub of the disc 115 is extended and this eraten'sion is formed with the four radial arms 118, each arm having slidahly mounted thereon a circular member 119, 119, 119

and 119 respectively. Preferably radial arm 118 has graduations thereon as shown so that the members 119,, 110, 119 and 119 is adapted to engage the upper edge of the bar 104 when brought into proper position by the rotation oi the disc 115. it. pawl 120'is' pivotally supported by the reciprocating bar and supported by a rest 121. The pawl 120 will engage the wheel 115 upon movement of the bar 50 in one direction.

Referring to. Figures 15, 1'? and 18, 122 indicates in each figure a pair of patterns and 123 the material therebetwecn. planation relative to forming these patterns will later be given.

In Figure 17 each side plait comprises two plies of sheet material 126 and 19.6 and the'box a single ply of sheet material 127. Ply 126 is of less width than ply 126. Assuming it is intended to make the pattern shown in Figure 17, the sheet of paper constituting the roll of paper R is extended between'the rollers R and also extended fun ther forward and between the crimping bars 23. The members 119 and 119 are so adjusted that when they come in contact with the bar 104, its curved portion 106 will be insuch a position that the power stroke of pawl 52 will be partially lost, and the roleach lers R will feedthe f paper .a distancef'equal to the" width of' ply 12 6". -Members'119 v ther'assuined that uponth'e starting- 0f said motor, the position of the arm"55 is? as shown in Figure'l, and that also the position of the bars 35"i's as illustrated in'this figure; The motor should rotate insuch' a direction that'the' cam wheels 15 and also the cam wheel 59 will rotate in an anti-clockwise direction. With the rota-tion of the shafts S" and S the arm 55 will first be actuated and the bar 50 moved forward to its extreme'fon ward position whenfth'e roller 57 of the arm is disposed in one of the protrusions 61' of the groove 58. The pa'wl120 will also during this interval rotate the" disc wheel 115 so that the member 119 will engage the bar 104'and swing the same'downwardly a certain degree. The amount'which the arm will be swung downwardly is as illustrated in Figure 7 of the drawings.

As seen in'dotted lines in'this figure, the V pawl 52 is at the extreme forward position and due to its width the same will rest on the curve portion'106 of bar 104. Now as the roller 57 of the bar 55 moves from the protrusion 60 ofthe groove 58, the recipro'-'- eating bar 50 will move' rearward1y and the pawl 52 after losing part of its stroke on curve portion '106will come in contact with teeth 49, thereby causing the ratchet wheel 47 to rotate in'- an "anti-clockwise direction whereby the rollers "R are rotatedto draw the paper from the T0113 forwardly a distance equal to 'thewidt'h of ply 126, Figure 17. After the roller'57 of the arm 55 is clear of the protrusion 60 a crimping operation will take place of the paper disposed between the crimping members 23. -At this interval the rollers-43 carried by the bar'41 will enter "in one of the protrusions 18, and thereby raise the bar 35. 'VVith this happening the ins of the I'Ol.le1"R* will'move into the upper endportion of'the slots 27, and the pins journaling the rollerlt' will moveiiito the upper end portion of the slots 26 and during this movement will roll upon the aicuate surface 24 oftlie crimping member 23, and thus causeacr'impof paper as illustrated in dottedlines o'fFi'gu're 5. During this operation "the cams 15' continue to revolve and therollers 40 m'dve'out'of protru'sions. 18. In this'way the crimping'rollers are permitted to return to original position. As the operation of the machine continues the roller carried by the arm 55 will move into one of the protrusions 61 and again reciprocate the bar 50, causing pawl 120 to rotate disc wheel 115 and causing member 119 to adjust curved. portion 106 of bar 104 so that pawl 52 will lose part of its stroke on curve portion 106 of bar 104 before coming in contact with teeth 49 thereby causing the rollers R to feed the paper a distance equal to ply 126, Figure 17, between members 23. Now as the roller 57 of arm 55 passes protrusion 61 roller 43 of arm 41 will move into a depression 17, as indicated in dotted lines in Figure 6 of the drawings and with this occurring the pin journaled in the roller R will move into the lower end portion of slots 26, while the pins journaling in the roller R will move into the lower end portion of slots 27, and with this movement will roll upon the arcuate surface 24 of the crimping member 23, and thus crimp the paper in the opposite direction. As the machine continues to operate member 119 will next actuate a crimp similar to the first crimp made and member 119", a crimp similar to second crimp made, etc., making the pattern with side plaits until stopped by pin 99 striking member 97 carried by rod 91. When the pin 99 strikes member 97 carried by rod 91, the rod 91 is pushed forward and the member 72 released. This member 72 will revolve under the force of the spring 76 onehalf turn or until the switch casing 83 engages the sleeve 94 carried by rod 91. This casing is so held by spring 84' that the depressible portion of finger 86 will be pressed inby sleeve 94 and open the circuit of motor M to stop the machine. When member 72 revolves this half turn under the force of spring 76, pin 101, in groove 102 follows excentric groove 100 moving bar 102 downward and carrying with it bar 104 due to pin 11.1 as shown in Figure 4. thus giving a greater stroke on the teeth 49 of the gear wheel 47.

By adjusting arm 63 before starting machine, the position of pin 101 may be changed with respect to arm 102 and as is apparent this adjustment will regulate the width of box plaits. Disk 15 is now manually moved from position as shown in Figure 5 to position as shown in Figure 6 or vice versa, as sometimes is the case causing the crimp at each side of the wide box to be made in the same direction. In the operation of this automatic stop and large plait regulator, one of the strokes of one of the members 119 or 119 or disc wheel 115 is lost as bar 102 has carried bar 104 below the reach of the member. The ma chine may be started by manually turning member 83, releas ng arm 86, and thus making the electric circuit for motor M.

On turning the member 83 by head 84 the motor circuit is again established. The pawl 52 takes its long power stroke and pin 99 depresses member 97 a sufficient distance to permit pin 99 to slide beneath 97 and permits rod 91 to return to original position and thereby release member 83 and permit casting 72 to return to its orig inal position. The turning of casting 72 is stopped by latch member 92 engaging lug 93. The machine may now be operated to complete the pattern. In this last operation the short ply 126 is first made and the ply 126, etc, as shown in Figure 17.

In making an accordion plait pattern as shown in Figure 18 pin 99 is removed, thus the automatic stop and long plait regulator is not used. Members 119, 119 and 119 and 1190 are adjusted alike, and all plaits will be of the same width. Another way to make all plaits the same size is to set bar 104 so that pawl 52 will not engage the same and adjust pawl 52 to produce the width desired.

In making a box plait pattern as shown in Figure 16, the automatic and wide plait regulator are not used. In this instance. members 119 and 119 on disk 115 would be set for the longest power stroke of pawl Members 119 and 119 for the shortest stroke. Cam wheels of the form shown in Figure 14 are substituted for cam wheels 15 in order to produce the proper creasing for a pattern of this kind.

Other plait-s or combination of plaits can be made as the one way side which is the same as the plaits on either side of the box in Figure 17 or combinations can be made by using a plurality of pins 99.

It may be here noted that the roll carry ing the material or paper from which the forms are made might be arranged to, re lease or give off two or more sheets and thus to produce two or more forms with one operation of the machine. This is entirely apparent, and no structure need be shown to illustrate the same. Referring to Figures 2 and 3, at 131 is ind cated a trough for water. This trough extends transversely of the paper 20 and with this trough, there is associated a wick 132 which engages the sheet of paper 20 therebeneath. It has been found the wick 132 will moisten the paper and. prevent cracking of the fibre therein during cr mping operations.

While I have here-in shown and described 7 the preferred form of my invention, I wish it to be understood that I am aware of the fact that the construction, combination and arrangement of parts may be changed by those skilled in the art without departing from the spirit of the invention as indicated ISO scribed, a p'air'of stationary members bean arcuate surface and said members being arranged parallel and spaces suitably for feeding a sheet of paper therebetween, and a pair of connected rollers adapted to move over the arcu-ate faces of said stationarymembers and transversely crimp the paper passing therebetween.
